Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a sterile curtain. Background Art

[0002] In most robot-assisted surgeries, one or more surface incisions are first made on the patient's body to provide entry points for various surgical instruments and endoscopes. The cannula is inserted into the patient's body cavity through the patient's surface incision, providing a channel for various surgical instruments and endoscopic instruments to enter the patient's body cavity for various external surgeries. The cannula is in direct contact with the wound surface and tissue of the human body and needs to be cleaned, disinfected and sterilized, but the robot's robotic arm end is usually designed to be non-cleanable, non-disinfectable and sterilized. In order to ensure the sterile conditions of the operation, a sterile curtain needs to be set between the robotic arm end and the cannula during the operation to isolate the non-sterile robotic arm end from the cannula used during the operation.

[0003] The module connecting the robot arm and the cannula can be called a cannula fastening module, and the part connecting the sterile curtain and the cannula fastening module is called a sterile adapter. The sterile adapter can be firmly combined with the cannula fastening module. After the sterile adapter of the sterile curtain is firmly clamped on the cannula fastening module, the cannula can be installed on the cannula fastening module equipped with the sterile adapter.

[0004] The cannula fastening module is docked with the cannula after docking with the sterile adapter. The fastening effect of the cannula fastening module on the cannula may be reduced due to the isolation effect of the sterile adapter.

[0005] To this end, the present application provides a sterile adapter to at least partially solve the problems in the prior art. Utility Model Content

[0043] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0044] In order to thoroughly understand the embodiments of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. It should be noted that the ordinal numbers such as "first" and "second" cited in this application are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component". The terms "upper", "lower", "front", "back", "left", "right" and similar expressions used in this application are for illustrative purposes only and are not restrictive.

[0045] Reference Figure 1 The present application provides a surgical robot 100. The surgical robot 100 includes a main control operation device 110 and an adjacent mechanical system 120. The main control operation device 110 and the adjacent mechanical system 120 are connected by communication. The main control operation device 110 can receive the doctor's operation instructions and issue control instructions to the adjacent mechanical system. The adjacent mechanical system 120 receives the control instructions of the main control operation device and performs the surgical operation.

[0046] In the para-patient robotic system 120, the surgical instrument 130 is generally configured to be removably mounted on the robotic arm 121. Figure 2 and Figure 3 The cannula 140 is a guide device for inserting the surgical instrument 130 into the patient's body. The cannula 140 is configured to be removably docked with the robotic arm 121. The robotic arm 121 is provided with a cannula adapter 122, which is a cannula fastening module. In implementation, the cannula adapter 122 includes a clamping structure, and the cannula 140 has a clamped structure. The clamping structure of the cannula adapter 122 can clamp the clamped structure of the cannula 140 to achieve the fixation of the cannula adapter and the cannula.

[0047] When the para-patient mechanical system 120 is performing surgery, the patient can be isolated from the para-patient mechanical system by using a sterile curtain 150. Usually, the sterile curtain 150 isolates the mechanical arm 122 of the para-patient mechanical system from the outside world, and accordingly, the sterile curtain 150 also needs to isolate the cannula adapter 122 and the cannula 140.

[0048] Specifically, when the cannula 140 is installed to the cannula adapter 122, a sterile isolation device, i.e., a sterile adapter, is provided between the cannula 140 and the cannula adapter 122. When the cannula 140 is fixed to the cannula adapter 122, it is necessary to first dock the sterile adapter to the cannula adapter 122, and then dock the cannula 140 to the sterile adapter, thereby achieving the function of fixing the cannula adapter 122 to the cannula 140.

[0049] In an embodiment of the present application, the sterile curtain 150 includes a sterile curtain body 10 and a sterile adapter 20. Among them, the sterile curtain body 10 is the part that covers the robotic arm 121, and the sterile adapter 20 is used to isolate the cannula 140 and the cannula adapter 122. The sterile curtain 150 has an inner side and an outer side. The inner side of the sterile curtain 150 is the side facing the robotic arm, or the inner side of the sterile curtain body 10 is the side facing the robotic arm, and correspondingly, the inner side of the sterile adapter 20 is the side that fits the cannula adapter 122; the outer side of the sterile curtain 150 is the side facing away from the robotic arm 121, or the outer side of the sterile curtain body 10 is the side facing away from the robotic arm 121, and correspondingly, the outer side of the sterile adapter 20 is the side facing away from the cannula adapter 122. Among them, refer to Figure 4 The sterile adapter 20 includes a first part 21 and a second part 22, wherein the first part 21 is used to be fixed to the cannula adapter 122, and the second part 22 is used to cooperate with the cannula 140. The first part 21, the second part 22 and the sterile curtain body 10 are all constructed as films. In the embodiment, the structure of the sterile adapter 20 is all made of films. Compared with the prior art, the sterile curtain in the present application has a simple molding process, a single material, low cost, and low biocompatibility risk.

[0050] In one embodiment, the cannula adapter 122 includes an outer surface with a regular structure shape, and the first part 21 of the sterile adapter 20 can cooperate with the outer surface of the cannula adapter 122. The first part 21 can include a first cylindrical portion 211 surrounding the outer periphery of the cannula adapter and a first straight portion 212 covering the cannula adapter and facing the cannula direction, and the first cylindrical portion 211 extends from the outer periphery of the first straight portion 212 in a direction perpendicular to the first straight portion 212. That is, the first straight portion 212 and the first cylindrical portion 211 are jointly enclosed to form a cylinder structure with at least a part of the bottom, and the cylinder structure has an inner cavity, and the cannula adapter 122 can be placed in the inner cavity, so that the cylinder structure and the cannula adapter 122 form a match. Compared with the structure of the existing sterile adapter, in this embodiment, the buckle and button structures provided on the cannula adapter can be eliminated, the volume of the cannula adapter can be reduced, and the miniaturization requirements of the robot arm can be at least partially met. Furthermore, in an embodiment, the first cylindrical portion 211 and the first straight portion 212 may fit the shape of the sleeve adapter exactly.

[0051] Accordingly, in one embodiment, a bowl-shaped insertion portion 141 protrudes from one side of the sleeve 140, the clamped structure 141a of the sleeve 140 is located in the insertion portion 141, and the second portion 22 of the sterile adapter 20 is adapted to the shape of the bowl-shaped insertion portion 141. Specifically, the first straight portion can define an insertion port 23, and the second portion 22 extends from the insertion port 23 toward the inner cavity of the first cylindrical portion 211, and closes the inner cavity.

[0052] Further, in the embodiment, the sterile curtain body 10 includes a second cylindrical portion 102, the second cylindrical portion 102 can form a covering for the mechanical arm 121, and a first area 101 is connected between the second cylindrical portion 102 and the first cylindrical portion 211, and the first area 101 extends from the edge of the first cylindrical portion 211 to the edge of the second cylindrical portion 102. In the implementation, in order to adapt to the irregular shape of the mechanical arm and the convenience of the sterile curtain 150 in the installation process, the sterile curtain body 10 is wider, and the cooperation with the mechanical arm 121 will have a larger gap space. Therefore, the sterile curtain body 10 has a transition area connected to the sterile adapter, and the first area 101 is the transition area. Therefore, the projection of the second cylindrical portion 102 on the plane where the first straight portion 212 is located is larger than that of the first cylindrical portion 211. Further, the first area 101 is constructed as a straight structure, and the straight structure of the first area 101 is parallel to the first straight portion 212. That is, the lengths of all generatrixes of the first cylindrical portion 21 of the first part 21 are the same.

[0053] In some embodiments, reference Figure 3 and Figure 4 , the sterile curtain 150 also includes a first fastening belt 24. The first fastening belt 24 can more firmly match the sterile adapter 20 with the sleeve adapter. Specifically, at least part of the first fastening belt 24 is fixedly connected to the outer surface of the first part 21, and one end or both ends of the first fastening belt 24 are free ends. The extension length of the first fastening belt 24 can at least circumferentially surround the first part 21 for one week, or in other words, the extension length of the first fastening belt 24 can at least circumferentially surround the sleeve adapter 122 for one week, and the two ends of the first fastening belt 24 can be butted, tied or fixed. The first fastening belt 24 can be a tie belt, a magic belt, etc., and the fixing method of the two ends of the first fastening belt 24 can be a knot, a clamping, an adhesive, a magnetic suction, etc. Further, the first fastening belt 24 can be fixed to the first cylindrical portion 211, and the extension length of the first fastening belt 24 can at least circumferentially surround the first cylindrical portion 211 or the sleeve adapter 122 for one week.

[0054] In one embodiment, reference Figure 5 and Figure 6The first part 21 can be integrally formed with the sterile curtain body 10. Specifically, the first part 21, the first region 101 and the second cylindrical portion 102 can be integrally formed. For example, the first part 21, the first region 101 and the second cylindrical portion 102 are formed at one time by a vacuum forming process.

[0055] Further, in one embodiment, referring to Figure 6 The first part 21 and the second part 22 can be processed separately and then joined together. For example, the first part 21, the first area 101 and the second cylindrical part 102 are processed and formed at one time by a vacuum forming process, and the second part 22 is processed separately, and then the two are joined by one or more processes such as bonding, hot pressing, drawing or pressing.

[0056] Further, refer to Figure 6 The second part 22 includes a second straight portion 221 and a receiving portion 222. The receiving portion 222 is adapted to the shape of the insertion portion 141 of the sleeve 140. The second straight portion 221 extends outward from the receiving port. The second straight portion 221 and the first straight portion 212 of the first part 21 can at least partially overlap. The second straight portion 221 and the first straight portion 212 are joined together by bonding, hot pressing, pulling or pressing.

[0057] In another embodiment, referring to Figure 5 The first part 21 and the second part 22 are integrally formed. For example, the first cylindrical part 211, the first straight part 212 and the second part 22 of the first part 21 are formed at one time by a vacuum forming process.

[0058] Further, refer to Figure 5 In one embodiment, the sterile curtain body 10 and the sterile adapter 20 are integrally formed. For example, the second cylindrical portion 102, the first region 101, the first portion 21 and the second portion 22 of the sterile curtain body 10 are formed at one time by a blister process.

[0059] Alternatively, in one embodiment, the sterile drape body 10 and the sterile adapter 20 are processed separately and then joined together. For example, the sterile drape body 10 and the sterile adapter 20 are processed separately by a blister process, and the two are joined by one or more processes of bonding, heat pressing, pulling or pressing.

[0060] In one embodiment, referring to Figure 5The second part 22 of the sterile adapter 20 also includes a protrusion structure adapted to the clamped structure 141a of the sleeve 140, and the protrusion structure is a protrusion 222a facing the outside of the sterile adapter. In another embodiment, the second part of the sterile adapter may not be provided with a protrusion, but deformed by force due to the properties of the material itself, and then deformed into a shape adapted to the clamping structure of the sleeve adapter.
